Osborne  Bumper  Disk  Harrow 

The  Osborne  Bumper  will  appeal  most  favorably  to 
the  farmer  who  desires  a  bumper  type  of  disk  harrow, 
because   it    is    the   only    bumper   disk  harrow 
with  a  solid  one-piece  main  frame.     There  are  no 
loose  connections  to  permit  unnecessary  play  of 
the  disk  gangs.     The  frame  is  one  con- 
tinuous piece  of  angle  steel,  pivoted  to 
the    bearings 
directly  over 
and  back  of  the 
center  of  the 
disks.     This    construction 
permits  the  use  of  a  one- 
piece  frame,   and   gives   the  Osborne 
Bumper  every  advantage  of  the  rigid 

frame  and  none  of  the  disadvantages  which  are  common  to 
the  ordinary  bumper  disk  harrow.    This  frame  withstands  hard 
usage  and  holds  the  gangs  in  place  so  that  they  do  good  work 
in  hard  ground,  and  should  it  ever  become  necessary  to  weight 
the  frame  it  will  stand  this  additional  weight.     There  are  no 
castings  on  the  ends  of  the  frame  and  it  is  not  excessively  heavy. 
This  frame  being  attached  back  of  the  center,  carries  the  driver 


Osborne  Bumper  disk  harrow 


with  none  of  his  weight  on  the 
horses'  necks.      This   also  has  a 
tendency  to  force  the  disks  into 
the    ground.      The   hitch    is  at- 
tached in  a  direct  line  of  draft 
giving  the  team  every  advantage 
of  a  straight  pull.    The  two  angle  steel  bars 
used  to  connect  the  center  of  the  cross  beam 
to  the  draw  frame  make  an  exceptionally  solid  brace 
for  the  frame,  permit  the  tongue  to  be  set  to  one 
side  for  three  horses,  without  the  use  of  a  stub  pole,  and  form 
a  substantial  rest  for  the  lever  quadrants. 


The  Osborne  Bumper  disk  harrow  is  the  only 
type  of  bumper  disk  harrow  with  a  one-piece 
frame.     Note  its  simplicity  and  strength

Bumpers  Rolling  Together   Relieve  the  Bearings 

of  End  Thrust 


On   the  Osborne  Bumper    disk    harrow, 
heavy  metal  bumpers  are  placed  on  the  inner 
ends  of  the  disk  gangs  so  that  the  bumpers 
roll  together  and  take  all  end  thrust  off  the 
bearings.    This  naturally  make?     5  harrow 
much  lighter  in  draft,  increases    .e  dura- 
bility of  the  bearings,  and  relieves 
the  frame  of  a  great  many  strains 
which  would   be  put  upon  it 
were  the  bearings  required 


f'^^VUu 


to  sustain  the  end  thrust  of  the  gangs — all  of 

which  adds  to  the  durability  of  the  harrow. 

The    Osborne    Bumper    disk     harrow    being 

equipped  with   a  rigid  frame,  overcomes  a 

common  fault  of  the  average  bumper  disk 

harrow  in  that  when  the  gangs  of  the  ordi- 

harrow  are  set  at  extreme  cutting 

igles,  the  disk  blades  come  togeth- 

instead  of  the  bumpers,  making 

them  liable  to  breakage. 


Pivot  Point 


-;         PiVDT  Point 


Pivoting  the  gangs  back  of  center  permits  the  bumpers  to  roll  together   without   joints  in  the  frame 


Adjustable  Snubbing  Block 

The  snubbing  block  on  both  the  Osborne  Bumper  and 
Rival  disk  harrows  are  adjustable;  that  is,  they  can  be 
adjusted  to  take  up  any  looseness  or  wear  that  may  take 
place,  so  that  the  gangs  will  always  be  kept  perfectly  level. 
If  good  work  is  to  be  done  with  a  disk  harrow,  it  is  abso- 
lutely necessary  to  have  level  gangs.  One  very  frequently 
sees  a  disk  harrow  that  is  either  penetrating  the  ground 
deeper  at  the  inner  ends  of  the  gangs  than  the  outer,  or 
vice  versa.  This  means  that  the  gangs  are  not  level  and 
that  the  harrow  is  not  disking  the  ground  at  a  uniform 
depth.  With  this  adjustable  snubbing  block  on  Osborne 
disk  harrows,  the  operator  can  keep  his  gangs  perfectly 
level  whether  the  harrow  has  been  in  operation  one  month 
or  years.  He  not  only  disks  at  an  even  depth  but  also 
levels  the  ground. 


Snubbing  block  is  adjustable.     The   bumpers   rolling 
together  relieve    the  bearings   of   end   thrust 


Oiling  Facilities  Are  Convenient 


The  oil  holes  on  the  bearings  of 
the  Osborne  Bumper  disk  harrow 
are  placed  directly  over  the  cen- 
ter, giving  the  oil  an  opportunity 
of    reaching   every   part  of    them. 
The  oil  pipes  extend  to  the  top  of 
the  frame,  and  are  fastened  in  such 
a  way  that  they  can  be  quickly  and 
easily  removed   and    the  bearings 
cleaned  without  any  difficulty  what- 
ever.   These  bearings  are  equipped 
with  wood   bushings,  which  can 
easily  be  replaced  at  a  shght  cost 
should  they  become  worn.      On 
special  order,  at  a  slight  additional 
price,  the  Osborne   Bumper       ^^^ 
disk  harrow  will  be  equipped 
with  hard  oil  cups.

bearings  over  the  center

Scrapers  Clean  the 
Disks 

The  Osborne  Bumper  and  Rival 
disk  harrows  are  equipped  with  the 
rocking  style  of  scraper,  operated 
by  foot  levers  within  convenient 
reach  of  the  operator's  feet.  These 
scrapers  clean  the  disks  from  the 
]  center  to  the  outer  edge,  and  while 
they  are  cleaning  the  entire  surface 
of  the  disk  they  clean  themselves 
as  well.  This  means  that  trash  does 
not  clog  the  scrapers  or  wind  around 


Any  scraper  can   be    removed    without    taking    off 
the  scraper  bar  or  any    of   the   other  scrapers 


the  axles.  The  blades  are  of  a  high 
quality  of  spring  steel  and  fastened 
so  that  each  one  can  be  removed  with-  l[|? 
out  taking  off  the  scraper  bar  or  any 
of  the  other  scrapers.  The  foot  lever 
end  is  fitted  with  a  set  screw  which 
strikes  on  top  of  the  gang  frame.  This 
construction  prevents  the  operator  from 
twisting  the  scraper  bar  by  putting  too 
much  pressure  on  the  foot  lever.  This 
set  screw  is  adjustable  so  that  the  stroke 
of  the  scraper  blades  can  be  made  long 
or  short,  as  the  operator  desires. 


Rocking  scraper  moves  from  the  cen- 
ter to  the  outside  of  the  disk,  clean- 
ing the  entire  surface

The  Osborne  Cutaway  Disk  Harrow 


The  Osborne  Bumper  and  Rival  harrows  are 
furnished  with  cutaway  disks  when  ordered,  and 
furnished  in  the  same  sizes  as  the  regular  harrow. 
The  difference  in  the  working  qualities  of  the  cut- 
away and  plain  disks  is  that  the 
cutaway  type  penetrates  deeper  into 
the  ground  and  throws  it  up  in  much 
coarser  condition  than  the  plain 
disk.  In  some  localities  the  cuta- 
way disk  harrow  is  preferable.  The 
scrapers  that  are  used  with  the  cut- 
away disk  harrows  are  of  a  special 


shape  and  type.     They  are  very  efficient  in  keep- 
ing the  disks  clean. 

The  Osborne  Rival,  plain  and  cutaway,  and 
the  Osborne  Bumper,  plain  and  cuta- 
way harrows,  are  furnished  in  the  fol- 
lowing sizes:  8,  10,  12,  14,  16  disks,  16 
18,  or  20  inches  in  diameter.

Osborne  Rival  Disk  Harrow 


The  Osborne  Rival  disk  harrow  will  do  good  work  in  ground  where  the  ordinary  disk  harrow  fails. 
It  has  long  been  the  standard  type  of  the  rigid  frame  disk  harrow.  Most  any  disk  harrow  will  do 
reasonably  good  work  in  soft  ground,  but  when  it  comes  to  disking  stubble  before  plowing  in  the  fall, 
disking  meadows  in  the  early  spring  before  plowing,  the  ordinary  disk  harrow  is  not  strong  enough  to 
do  this  work  satisfactorily.  The  exceptional  rigidity  and  strength  of  the  Osborne  Rival  disk  harrow 
frame  holds  the  gangs  to  their  place  so  that  good  disking  can 
be  done  in  this  kind  of  ground.  It  stands  to  reason  that  if 
a  harrow  will  do  good  work  in  hard  ground,  it  will  in  soft. 
Consequently,  when  a  farmer  purchases  an  Osborne  disk 
harrow,  he  has  one  which  gives  him  good  service  in  all 
kinds  of  soil.  The  draw  bar  frame  is  one  continuous 
piece  of  bar  steel  and  is  fastened  to  the  standards 
of  the  disk  gangs  near  the  center  of  the  disks, 
making  a  direct  center  draft  which  keeps 
the  harrow  in  perfect  balance,  regardless 
of  the  driver's  weight.    There  are  no  /  /  (_ 

castings  on  the  corner  of  the  frames 
to  break  and  cause  endless  annoy- 
ance. The  two  steel  angle  bars  riv- 
eted to  the  centers  of  the  cross  bar 
and  draw  frame  in  front  make  the 
frame  exceedingly  rigid.  These 
angles  serve  as  a  rest  for  the  seat 
and  center  tooth,  a  support  for  the 
adjusting  lever,  and  take  the  place 
of  the  stub  pole  when  the  tongue  is 
set  to  one  side  for  three  horses. 


Center  Tooth  Cultivates  and  Levels  Ridge 
Between  the  Gangs 


The  Osborne  Rival  disk  harrow  is  equipped  with  a 
spring-tooth,  pivoted  back  of  the  seat  support  to 
cultivate  and  level  the  ridge  of  ground,  between 
the  disk  gangs.  The  tooth  is  adjustable  for  deep  or 
shallow  cultivation  and  can  be  raised  high  from  the 
ground  for  transportation.  This  construction  over- 
comes the  objection  that 
the  disk  harrow,  that  it 
does  not  cultivate  all  the 
ground.  The  Osborne 
Rival  does.

Bearings 


The  bearings  on  the 
Osborne  Rival  disk  har- 
row are  provided  with 
large  center  ring  projec- 
tions which  relieve  the 
ends  of  the  bearings  of 
end  thrust,  eliminating 
extra  draft  and  wear. 
The  bearings  are  chilled, 

making  them  durable  and  The  center  tooth  cuh.vates  and  levels  the  rid.e   between  the  gangs 

they  are  large,  giving  ample  bearing  surface.  The  oil  hole  in  the  bearing  standard  opens  in  the  groove 
in  the  center  and  is  large.  This  groove  forms  a  channel  for  the  oil  to  flow  down,  giving  it 
an  opportunity  to  spread  out  over  every  part  of  the  bearing.  These  bearings  will  never 
wear  out  if  they  are  kept  properly  oiled.  They  are  as  nearly  dust  proof  as  it  is  possible  to 
make  a  disk  harrow  bearing.  The  dust  bands  which  fit  over  the  ends  of  the  bearings 
prevent  falling  dirt  from  working  in. 

Transport  Trucks  for  Disk  Harrows 

On  special  order,  at  a  slight  additional  cost,  the  Osborne  Rival  and  Bumper  disk  har- 
rows will  be  equipped  with  a  truck 
for  transportation.  These  trucks  pro- 
tect meadows  from  being  cut  by  the 
disks  a  n  d 


prevent 
the  disks 
from  being 
blunted  on 
the  edge  by  coming  in  contact  with 
hard  roads,  stones,  etc.  These  trucks 
can  be  thrown  back  over  the  harrow 
out  of  the  way  when  at  work  in  the 
field.  The  harrow  can  be  mounted 
very  quickly  and  easily.

bearing  relieves  the  end  of  the 
bearing  of  end  thrust

Osborne  Orchard  Disk  Harrow 


The  Osborne  Orchard  disk  harrow  is  a  first-class 
implement  for  the  fruit  grower  because  it  enables  him 
to    work    close  to  the  trunks  of    the  trees  without 
injuring  the  leaves,  branches,  and  fruit  of  low-hanging 
boughs.    This  implement  can  be 
used  also  as  a  regular  disk  harrow 
and    for    building  up  irrigation 
ridges,  tearing  them  down,  and 
other    innumerable   purposes  of 
this  character.     It  is  also  a  good 
implement  for  use  in  vineyards.

frame  euid  inner  ends  raised  higher  than  the  outer 


Main  Frame  Construction 

The  main  frame  is  placed  directly  in  front  of  the 
center  of  the  disk  gangs,  making  it  so  low  that  it  will 
readily  pass  under  low-hanging 
branches.  The  two  steel  angle 
cross  sills  shaped  in  the  form  of  a 
goose  neck  in  f"ont  make  this 
frame  exceptionally  rigid  and  hold 
the  entire  frame  almost  parallel 
with  the  ground  so  that  the  front 
easily  passes  under  low  boughs. 


Gangs 


The  gangs  can  be  changed  so  that  the  harrow  will 
throw  dirt  toward  the  center  or  away  Irrrii  the  center. 
The  cutting  angles  are  controlled  by  levers  which  are 
so  situated  that  they  do  not  catch  on   branches  and 
leaves.    They  work  forward  and  back  the  same  as  on 
the  regular  disk  harrows  and  not  at  right  angles  to  the 
gangs,  thus  keeping  the  levers  free  from  coming  in  con- 
tact   with    branches.    Both    gangs 
are  equipped  with  shields  which  pre- 
vent low  hanging  limbs  and  twigs 
from  coming  into  contact  with  the 
disks.     Hard   oilers   are   used,   per- 
mitting the  use  of  hard  oil.

Note  also  that  the  levers 
are  convenient  to  the 
driver's  seat. 


Special  Features 

On  special  order,  at  a  slight  additional  cost, 
this  harrow  will  be  equipped  with  an  extension 
frame  which,  when  placed  on  the  harrow,  is  1 1  feet 
and  6  inches  from  the  outside  of  one  gang  to  the 
outside  of  the  other.  This  feature  in  connection 
with  the  fact  that  the  gangs  can  be  worked  higher 
or  lower  on  the  outer  than  inner  ends  and  vice 
versa  makes  it  possible  for  the  operator  to  use 
this  harrow  with  the  utmost  success  in  both  young 
and  old  orchards  without  injuring  the  trunks  of 
the    trees  or  cultivating  into  the  ground   deep 


Note  this  solid  gang  construc- 
tion. Bearings  are  equipped 
with  hard  oilers 

enough  to  harm  the 
roots.  Extension 
lever  bars  are  fur- 
nished with  extension 
frame.  These  enable 
the  operator  to  control 
the  gangs  on  the  ex- 
tension frame  the 
same  as  on  the  regular 
frame.

Forecarriage 

This  harrow  is  equipped  reg- 
ularly with  a  forecarriage,  descrip- 
tion of  which  is  given  on  the  next 
page.  This  forecarriage  can  be 
used  either  with  or  without  a  pole, 
as  the  purchaser  desires.  If  the 
pole  is  wanted,  it  will  be  furnished 
on  special  order  at  a  slight  addi- 
tional expense.

When  the  special  frame  is  at- 
tached, the  width  of  cut  over  all 
is  1 1  feet  and  6  inches. 


Forecarriage  for  Use  with  Osborne  Disk  Harrows 

The  forecarriage  for  use  with  the  Osborne  Bumper, 
Rival,  and  Orchard  disk  harrows  is  undoubtedly  the 
most  efficient  forecarriage  that  has  ever  been  placed  on 
a  disk  harrow.     It  has  more  adjustments  than   any 
other  truck  made.     Both  the  clevis  and  axle  standard 
have  up  and  down  adjustments,  which  permit  the  truck 
to  be  adjusted  to  any  size  disk, 
16-,  18-,  or  20-inch,  and  press  just 
firmly  enough  on  the  ground  to 
keep  the  harrow  running  steady 
without    interfering   with  the 
proper  suction  of  the  disks,  work 
of  the  harrow,  or  adding  draft  on 
account   of    the  wheels   digging 
into  the  ground. 

The  bearings  are  dust  proof 
and  fitted  with  hard  oilers.  One 
of  the  unique  features  of   this 

bearing  is  that  the  only  place  where  it  is  possible  for  dust  to  enter  is 
around  the  edges  of  the  collar  which  holds  the  bearing  on  the  axle.  By 
keeping  sufficient  grease  so  that  a  slight  amount  oozes  out,  it  keeps  the 
opening  filled  so  that  dust  cannot  enter  under  any  circumstances,  thus 
making  a  bearing  which  is  absolutely  dust  proof.  When  filling  these  oil 
cups,  it  is  not  necessary  for  a  particle  of  dirt  to  be  mixed  in  with  the 
grease,  because_th^  oil  cups  are  removed  emirely  from  the  wheels  when  being  filled.  The  cup  is 
'""  "^  placed  between   the  spokes,  making  it  impossible  for  the  obstructions 

to  loosen  it. 

A  pole  can  be  used  with  this  forecarriage  or  not,  as  the  purchaser 
desires.  If  he  needs  to  use  the  pole  when  transporting  the  harrow  over 
roads  or  going  from  one 
field  to  another,  this  can 
be  done  and  the  pole  re- 
moved when  working  in 
the  field.  The  pole  can 
be  set  in  the  center  for 
two  or  four  horses,  and 

to  either  the  right    or  left  i-ole  pUced  i„  .he  ce"„.;rfo"r"2  ori  h^rsT 

hand  side  for  three  horses,  thus 
enabling  the  operator  to  adjust 
the  pole  to  the  team  and  not 
the  team  to  the  pole,  as  is  usu- 
ally the  case  with  the  ordinary 
forecarriage. 

The  axle  is  pivoted  to  the 
axle  s  t  a  n  d  a  r  d,  giving   the

Osborne  Spring  Tooth  Harrow 


Osborne  spring  tooth  harrow 

The  spring  tooth  harrow  is  the  most  valuable  implement  for  loosening  up  tenacious  and  fine 
texture  soil,  for  leveling  inequalities  in  the  surface  of  the  ground,  for  destroying  weeds  which  have  not 
become  deeply  rooted,  for  cultivating  stony  and  gravelly  land,  for  loosening  up  fall-plowed  ground  in 
the  early  spring,  for  aerating  soil.  The  Osborne  spring  tooth  harrow  is  constructed  to  do  these  things 
in  the  most  efficient  manner. 

The  main  frame  of  each  section  is  constructed  of  angle  steel  and  bent 
upward  with  an  easy  slope  in  front  for  trash  clearance.  The  tooth  beams 
are  placed  high  and  one  section  is  cut  away  in  the  center  and  raised  for 
trash  clearance.  The  teeth  are  spaced  on  the  tooth  beams  so  that  trailing 
is  impossible,  thus  each  tooth  does  its  full  share  of  the  work.  The  tooth 
clip  which  holds  the  tooth  to  the  beam  is  made  so  that  the  strain  on  the 
tooth  comes  upon  the  beam  and  not  upon  the  bolt,  thus  eliminating  break- 
age of  tooth  bolts.  The  bottoms  of  the  frames  are  equipped  with  steel  run- 
ner shoes,  which  can  be  removed  when  they  become  worn,  thus  making  it 
impossible  to  wear  out  the  frame.  The  hitch  is  adjustable  to  make  the 
front  or  rear  teeth  work  deep  or  shallow,  as  conditions  require.  The  quad- 
rants have  fine  teeth  so  that  close  adjustment  of  the  spring  teeth  is  possible,  giving  the  operator  the 
chance  of  cultivating  at  just  the  right  depth.  On  special  order,  at  a  small  additional  price, 
these  harrows  will  be  equipped  with  reversible  double  pointed  teeth.  These  can  be  turned  end 
for  end  when  they  become  worn,  thus  giving  the  wearing  qualities  of  two  teeth  in  one.  These  harrows 
are  furnished  in  15, 17,  23,  or  25  teeth.  The  sections 
of  the  spring  tooth  harrow  are  hinged  together,  per- 
mitting the  harrow  to  follow  unequal  surfaces  of  the  "^gST  /^ 
ground  and  to  do  as  good  work  as  when  working  on  ^  *^ 
level  soil.

Osborne  Sulky  Spring  Tooth  Harrow 


The  spring  tooth  harrow  is  a  good  implement  for  loosening  up  the  soil.     Note  the  efficient  work  it  is  doing  in  this  field 


The  harrow  part  of  the  Osborne  sulky  spring 
tooth  harrow  is  identical  with  that  of  the  spring 
tooth  harrow  shown  on  the  opposite  page.  As  a 
matter  of  fact,  the  farmer  who  has  a  spring  tooth 
harrow  and  desires  to  equip  it  with  a  sulky,  can 
do  so  by  ordering  one.  The  17-  and  23-tooth 
harrows  require  the  same  size  sulky  and 
the  15-tooth  a  smaller  size.  When  ordering 
a  sulky  for  a  spring  tooth  harrow,  designate 
the  size  of  the  harrow.  This  sulky  attach- 
ment is  made  so  that  all  the  weight  of  the 


driver  can  be  put  on  the  harrow  or  taken  off;  thus  if 
the  operator  is  working  in  hard  ground  and  desires 
to  throw  his  weight  on  the  harrow,  he  can  do  so. 
The  wheels  are  within  the  harrow  and  are  placed 
£0  that  trash  does  not  catch  on  them.  They  are 
fitted  with  sand  bands  to  keep 
out  dirt.  These  wheels  being 
placed  within  the  harrow,  do 
not  track  the  harrowed  field. 
The  runner  shoes  in  front  and 
the  wheels  at  the  rear  keep  the 
teeth  cultivating  at  a  uniform 
depth.

Osborne  Combination  Harrow 


Osborne  combination  harrow 


The  Osborne  combination  harrow  is  in  reality  a  spring  tooth  and  peg  tooth  harrow  in  one.  The 
traihng  teeth  in  the  rear  smooth  the  ground,  breaiting  up  the  clods  while  they  are  fresh,  leaving  the 
ground  in  excellent  condition  for  drilling  or  planting.  The  main  frame  is  exceptionally  strong  and 
placed  high  from  the  ground  for  easy  trash  clearance.  The  teeth  are  made  of  a  high  quality  of  spring 
steel  and  are  fastened  to  the  tooth  beams  by  a  clamp  which  permits  them  to  be  adjusted  to  take  up 
wear,  thus  the  operator  can  keep  the  points  of  the  teeth  working  at  the 
same  depth,  whether  the  harrow  is  new  or  after  it  has  been  used  a 
number  of  years.  The  trailing  teeth  in  the  rear  and  the  swivel  shoes  in 
front  keep  the  harrow  running  steadily  and  the  teeth  cutting  at  a  uni- 
form depth.  Each  section  is  joined  to  the  draw  bar,  making  the  harrow 
flexible,  so  that  it  will  conform  to  unequal  surfaces  of  the  ground  and 
do  good  work.  The  tooth  bars  are  bent  upward  at  the  ends  where  they 
are  fastened  to  the  frame,  making  a  very  simple  and  exceptionally 
strong  construction,  The  lever  quadrants  have  fine  teeth,  permitting 
close  adjustments  of  the  spring  teeth.     The  trailing  teeth  in  the  rear  can  be  adjusted  so  that  more  or 

less  slant  can  be  put  upon  them. 
The  trailing  teeth  in  the  rear  and 
the  swivel  shoes  in  front  prevent 
the  harrow  from  tipping  up  when 
turning  short  corners. 

The  combination  harrow  is  fur- 
nished in  two  or  three  sections. 

The  two-section  harrow  cuts  5  ft.,  5  in.

Osborne  Vineyard  Spring  Tooth  Harrows 

The  Osborne  vineyard  spring  tooth  harrows  have  the  same  features  of  merit  as  the  regular  spring 
tooth  harrows.  They  are  furnished  with  7,  9,  and  12  teeth,  and  with  or  without  handles,  as  the  pur- 
chaser desires.  They  are  especially  adapted  for  use  in  fields  where  a  larger  spring  tooth  harrow  can 
not  be  used  to  advantage  and  in  vineyards,  orchards,  nurseries,  etc.

Osborne  Peg  Tooth  Harrow 


Osborne  peg  tooth  harrow 

The  Osborne  peg  tooth  harrow  stands  for  all  that  is  good  in  peg  tooth  harrows.  It  is  without 
question  the  strongest  and  most  durable  peg  tooth  harrow  that  has  ever  been  made.  Each  section  is 
equipped  with  strengthening  bars,  one  on  each  side,  which  makes  it  impossible  for  a  tooth  to  catch  on 
an  obstruction  and  bend  the  tooth  bar  to  which  it  is  fastened  without  bending  the  other  tooth  bars 
also.  This  means  that  it  is  next  thing  to  impossible  to  bend  a  tooth  bar  on  an  Osborne  peg  tooth 
harrow.     This  harrow  without  these  strengthening  bars  is  as  strong  as  the  ordinary  harrow. 

To  illustrate  the  great  strength  of  this  strengthening  bar,  the  salesman  in  the  accompanying 
picture  has  removed  the  bracket  connecting  the  tooth  bar  to  the  strengthening  bar.  Placing  the  tooth 
on  a  block,  he  stands  on  the  harrow  which  shows  very  plainly  what  must  happen  on  any  harrow  that 
does  not  have  the  strengthening  bar.  In  the  second  illustration,  he  has  placed  the  bracket  on  the 
harrow.  His  weight  does  not  affect  this  tooth  any  more  than  it  does  the  others.  The  first  picture 
vividly  illustrates  what  happens  to  the  ordinary  peg  tooth  harrow  and  is  the  great  reason  why  so  many 
of  them  have  bent  tooth  bars.  The  second  shows  why  one  never  sees  a  twisted  tooth  bar  on  an 
Osborne  harrow.

Osborne  Peg  Tooth  Harrow 


"fi^^^^^T^^f^^ 


The  Osborne  peg  tooth  harrow  is  equipped  with  four  runner  teeth,  one  on  the  outer  end  of  each 
section.  These  teeth  act  as  transports  for  the  harrow  when  passing  over  meadows  and  going  from 
one  field  to  another,  they  protect  meadows  from  being  torn  by  the  teeth  of  the 
harrow,  and  save  the  farmer  the  time  and  trouble  of  loading  the  harrow  onto  a  stone 
boat  or  putting  it  into  a  wagon. 

The  tooth  clips  are  forged  from  steel  and  are  fastened  with  two  nuts,  making  a 
very  strong  and  substantial  fastening.    The  teeth  have  upset  heads,  and  are  made  of 
a  special  quality  of  steel  tempered  for  this  purpose.    Each  section  is 
attached  to  the  draw  bar,  making  the  harrow  very  flexible,  so  that  it 
will  conform  to  unequal  surfaces  of  the  ground.     One  section  or  as 
many  as  the  operator  desires  can  be  attached  to  a  draw  bar.    The 
lever  quadrants  are  equipped  with  fine  teeth, 
which  permit  close  adjustments  of  the  har- 
row teeth. 

The  tooth  bars  are  made  U-shape,  and 
thicker  in  the  center  than  they  are  on  the 
edges,  thus  giving  exceptional  strength  and 
making  them  light  in  weight.    This  harrow  is 
furnished  with  23, 30,  or  35  teeth  to  the  section,  either  '  2 "  square,  or  5  ^"  diamond  shape.

Orchard  Guards 

On  special  order,  at  a  slight 
additional  expense,  the  Osborne 
peg  tooth  harrow  will  be  equipped 
with  orchard  guards.  These  guards 
prevent  the  outer  ends  of  the  tooth 
bars  from  catching  on  trees  and 
stumps.  They  also  prevent  the 
accumulation  of  trash  on  the  outer 
ends  of  tooth  bars. 


Riding  Attachment  for  Osborne  Peg   Tooth   Harrows 


Osborne  peg  tooth  harrow  equipped  with  sulky  attachment 


The  riding  attacliment  for  the  Osborne  peg  tooth  harrow  saves  the  farmer  many  steps,  thus  reliev- 
ing him  of  the  most  tiresome  work  that  a  farmer  has  to  do — that  of  walking  after  a  peg  tooth  harrow. 
This  attachment  is  composed  of  two  long  arms  which  fasten  to  the  draw  bar  of  the  harrow  and  an 
axle  which  is  made  so  that  the  wheels  turn  in  when  turning  corners.  This  enables  the  driver  to  make 
short  turns  without  the  wheels  sliding  or  tipping  up.  The  seat  is  so  arranged  that  the  rider  balances  the 
riding  attachment,  thereby  removing  all  weight  from  the  draw  bar.  The  wheels  are  made  of  steel 
with  staggered  spokes.  These  wheels  are  exceptionally  strong  and  are  high  enough  to  keep  the  driver 
out  of  the  dust.  The  bearings  are  equipped  with  hard  oilers,  permitting  the  use  of  hard  oil,  which  if 
properly  used  is  unquestionably  the  best  lubricant  for  bearings  of  this  character.  This  attachment  is 
always  in  the  line  of  draft,  consequently  it  does  not  disturb  the  good  work  of  the  harrow. 


This  farmer  is  saving  himsetf  many  weary  steps

Osborne  Cultivators 


Osborne  cultivator  No.  55 


Osborne  cultivator  No.  53 


Osborne  cultivators  are  made  for  all  purposes  where  a  one-horse  cultivator  is  required.  They  are 
equipped  with  different  attachments  which  enable  the  operator  to  do  good  cultivating  in  all  kinds  of 
crops.  These  cultivators  are  made  in  three  series.  Nos.  51,  52,  53,  54,  and  55  comprise  one  section; 
Nos.  71,  72,  73,  74,  and  75  the  second;     Nos.  91,  92,  93,  94,  and  95  the  third  series. 

The  frames  of  all  these  cultivators  are  made  the  same,  consequently  by  adding  different  attach- 
ments the  70  and  90  series  can  be  made  from  the  50  series,  thus  the  farmer  can  have  a  cultivator  for 
all  purposes,  enabling  him  to  do  the  best  cultivating. 

Cultivator  No.  .51  is  furnished  with  5  shovels  and  expansion  screw. 

Cultivator  No.  52  with  expanding  lever  and  5  shovels. 

Cultivator  No.  .53  with  5  shovels,  expanding  lever,  and  wheel  jack. 

Cultivator  No.  54  with  wheel  jack,  expanding  lever,  5  shovels.  2  mold  boards,  and  1  horse  hoe. 

Cultivator  No.  55  with  expanding  lever,  lever  wheel  jack,  5  shovels,  2  mold  boards,  and  1  horse  hoe. 

Cultivators  No.  51,  52,  53,  54,  and  55  can  be  expanded  from  12  to  25  inches.  These  cuhivators 
can  be  made  into  the  corresponding  Nos.  71,  72,  73,  74,  and  75  by  adding  two  shanks  and  shovels. 
The  frames  are  punched  for  this  purpose.

Osborne  Cultivators 


Osborne  cultivator  No.   75 


The  frames  are  made  of  bar  steel  and 
they  are  fastened  in  such  a  manner  that 
they  present  the  shovels  as  squarely  as 
possible  to  the  ground  whether  the  cultiva- 
tor is  expanded  or  closed.  The  shovels  are 
extra  thick  in  the  center.  This  makes 
them  strong  and  provides  ample  thickness 
for  the  holes  in  the  center  to  be  deep  and  square,  so  that  the  bolts  which  hold  them  to  the  shank  will 
not  turn.  The  shape  of  the  shovel  makes  it  fit  the  shank  so  closely  that  it  is  impossible  for  the 
shovel  to  turn,  insuring  that  the  shovel  will  be  solid  on  the  shank.  These  shovels  are  reversible, 
affording  two  cutting  surfaces.  The  shovels  being  thick  in  the  center  and  thin  on  the  edge,  wear  has 
no  effect  upon  the  original  shape.    They  will  retain  sharp  points  until  completely  worn  out. 

The  mold  boards  are  made  similar  to  the  mold  board  and  point  of  a  plow.  They  are  reversible 
the  same  as  the  shovels.  When  one  point  becomes  worn  the  other  can  be  used.  They  can  be 
adjusted  to  throw  dirt  towards  or  away  from  the  plants.  They  also  can  be  used  for  hilling  purposes. 
Cultivators  Nos.  71,  72,  73,  74,  and  73  can  be  made  into  corresponding  Nos.  91, 92, 93, 94,  and  95  by 
adding  two  expansion  bars,  shanks,  and  shovels.  These  cultivators  can  be  expanded  from  12  to  28  inches. 
They  are  furnished  the  same  as  the  50  series,  except  that  7  shovels  are  furnished  instead  of  5.

Osborne  cultivator  No.  95 


The  wheel  jack  is  exceptionally  strong 
and  is  made  so  that  the  teeth  can  be 
regulated  by  it  as  well  as  the  clevis  hook. 
The  clevis  locks  so  that  it  is  impossible 
for  a  singletree  to  come  out  when  the 
horse  backs. 

The  lever  wheel  jack  used  on  culti- 
vators Nos.  55,  75,  and  95  in  connection  with  the  expansion  lever  makes  it  possible  for  the  operator  to 
cultivate  between  rows  of  different  widths  without  stopping  the  horse  to  make  adju-siments.  This 
makes  these  cultivators  of  exceptional  value  to  the  truck  grower. 

The  improved  lever  expanding  device  holds  the  cultivator  (frames  exceptionally  rigid  whether  they 
are  closed  or  expanded,  and  the  teeth  are  so  spaced  that  close  adjustments  can  be  made  when  the 
cultivator  is  being  closed.  This  is  of  particular  value  because  it  gives  the  operator  an  opportunity  tc 
adjust  the  cultivator  to  varying  widths  of  rows  and  get  as  close  to  the  plants  as  he  desires. 

This  feature  of  the  Osborne  cultivator  is  a  great  contrast  to  the  ordinary  cultivator  of  this  type, 
and  is  a  feature  which  every  prospective  purchaser  should  look  into  very  carefully. 

Cultivators  Nos.  91,  92,  93.  94,  and  95  can  be  expanded  from  19  to  38  inches,  and  are  furnished 
with  the  same  equipment  as  the  50  series,  except  that  9  shovels  are  furnished  instead  of  5

Osborne  14-tooth  cultivator  is  particularly  desirable  for  use  in  cultivating  in  places  where  deep 
cultivation  without  stirring  the  ground  is  desired.  Consequently  it  is  a  good  implement  for  use  in 
cultivating  strawberries,  raspberries,  blackberries,  gooseberries,  hops,  vineyards,  etc.  This  cultivator 
is  furnished  with  a  zigzag  or  straight  bar  frame,  with  or  without  lead  wheel,  with  expanding  lever  or 
thumb  screw  expansion  as  the  purchaser  desires.  On  special  order  a  reversible  curved  in  tooth  will 
be  furnished  at  a  small  additional  price.    This  gives  the  advantage  of  two  sets  of  teeth  in  one,  because 

they  can  be  reversed  when  one  becomes  worn.     The  expanding  lever 

7  and  wheel  jack  are  the  same  as  those  used  on  5-7-9-shovel  cultivators 

/  and  have  the  same  features  of  merit.   The  tooth  clip  is  slotted  to  permit 

different  angles  of  slant.    This  enables  the  operator  to  adjust  the  teeth 

for  ground  in  all  conditions.
